Abstract: Examples disclosed herein provide methods and systems for the authentication of a print request. As an example, an email service associated with an enterprise network may receive an electronic message having a destination address indicative of a request to print data included in the message, wherein the destination address may have a domain name associated with the enterprise network. The email service may access an authentication service associated with the enterprise network to determine whether a sender address of the electronic message is a valid address to submit print jobs. Upon determining the sender address is a valid address, the email service may forward the electronic message to a cloud print service to prepare the print job comprising the data included in the message for printing.

Abstract: Examples disclosed herein relate to replacement text for textual content to be printed. Examples include a covert version of a document including textual content to be printed, the covert version including replacement text having, for each character of a plurality of first characters of the textual content, a corresponding second character having a different semantic meaning than the first character. The covert version also includes an encrypted representation of the textual content.

Abstract: Examples disclosed herein relate to generating a print format version with an overlaid machine-readable link. As an example, a set of machine-readable links assigned to a user account from a remote repository is obtained. In response to a print command associated with the user account, one machine-readable link from amongst the set of the machine-readable links is selected and applied onto a portion of the digital document. Thereafter, a print format version of the digital document along with the machine-readable link is generated.

Abstract: An example implementation includes an apparatus including a processor to divide a digital image into a grid including a first grid region and a second grid region. The processor is also to generate a first grid-based watermark using shared watermark information and a first set of grid coordinates associated with the first grid region. The processor is further to generate a second grid-based watermark using the shared watermark information and a second set of grid coordinates associated with the second grid region. The processor is further to embed the first grid-based watermark into a first region of the digital image corresponding to the first grid region and to embed the second grid-based watermark into a second region of the digital image corresponding to the second grid region. The processor is further to generate a machine-readable digital image including the embedded first grid-based watermark and the embedded second grid-based watermark.

Abstract: Example embodiments relate to recognizing embedded information from images. In this manner, the embodiments disclosed herein enable recognition of a first barcode from a first image and a first machine-readable watermark based on the first barcode. The first barcode may be decoded to obtain a first group identifier. The first machine-readable watermark may also be decoded. A first payload associated with the first machine-readable watermark may be accessed based on the first group identifier and a first reusable watermark identifier of the first machine-readable watermark.

Abstract: Examples disclosed herein relate to providing access to digital content using a machine-readable link. As an example, an annotation comprising digital content, for a portion of a digital content, is identified in response to a print request. Based on the annotations, a machine-readable link associated with the digital content is generated. Subsequently, a printable format version of the digital document comprising the machine-readable link, and excluding the annotation is obtained wherein the machine-readable link is readable by a computing device to obtain access to the digital content over a communication network.

Abstract: Systems and methods for printing a document over a network are described herein. In one implementation, a method for network printing comprises receiving a request from a node to connect to a parent node and determining whether a number of child nodes of the parent node has reached a predefined threshold number. The method further comprises transmitting a connection acknowledgement message to the node on determining the number of child nodes not to have reached the predefined threshold number.

Abstract: A system for secure printing is disclosed herein. An example of the system includes a client that initiates a print request, creates an identifier, transmits the print request and identifier, and renders print data. The system also includes a cloud-connected printer and a server to which the cloud-connected printer is coupled that receives the transmitted print request and identifier, verifies the availability of the cloud-connected printer, transfers the identifier to the available cloud-connected printer, and establishes a secure connection between the available cloud connected printer and the client. Other details of the system are disclosed herein, as are other examples of the system. Examples of a method for secure printing and a non-volatile storage medium are also disclosed herein.
